15. Cardinal Fish
Cardinal fish, a group of small tropical fish, possess a fascinating defense mechanism known as “spitting fire.” When they consume bioluminescent ostracods, tiny organisms that emit light, the cardinal fish’s bodies start to glow. However, to avoid drawing attention from predators, the cardinal fish quickly spits out these glowing creatures.
This behavior creates an illusion of spitting bursts of bluish fire, which serves as a diversionary tactic. By creating this visual spectacle, the cardinal fish confuses and startles potential predators, allowing them to escape and evade detection. This unique adaptation showcases the remarkable strategies that organisms develop to ensure their survival and protection in their marine habitats.
